摘　　要：针对水钢烧结机机头机尾除尘灰、高炉瓦斯灰和出铁场除尘灰等二次资源直接配入混合料中不好烧结的问题,进行了专题试验研究。通过造小球试验,考察了不同种类除尘灰造小球的成球性能、落下强度和爆裂粉化温度,并取得了理想的试验结果。Aimed at the problem of poor sintering results caused by directly adding of renewable resources from the head - and tail - dusts of the sintering machine, the blast furnace gas dust and the steel plant dust, etc. into sinte -ring mixed material, a specialized experimental research was carried out. Through a series of mini - pelletize experiments, the technical - economical indexes of the pelletizability, the strength of mini - pellet, the burst temperture,and others were examined, and satisfactory test results have been acquired. Moreover, a new way for rational utilization of these renewable resources was also found.
